How can the class mask (.cls file ) be created automatically?
I though that when we want to create a class mask (.cls) we

 enable the classmask tab and select regions on the map with the
polygon. a right mouse click will finish the selection and one class will
be created and shown in the tab.

When I have created all the classes I select to save the cls file=20
manually from the "class mask" tab.
Right or wrong? So how is a class mask file created automatically?


2.When I want to create the cls file for the test set sometimes when I=20
select classify the .cls file is not created automatically.
I think that sometimes the cls file is created in the "classes" tab and=20
can be saved from there.
Right or wrong?

3.Sometimes when I load an .lrn file and select to perform=20
z-transformation the file that is created includes non readable=20
characters and I cannot explain why is this happening.

4.The whole procedure of training with a train set creating a class=20
mask, projecting a test set and creating a new cls file for the train=20
set belong is the category of unsupervised classification?


Thank you in advance for your valuable help,
Katerina
